Failure recovery service targets embedded Linux

Mar 19, 2009 — by Eric Brown — from the LinuxDevices Archive — views

Lineo Solutions has launched a failure analysis service for embedded Linux developers. The “LL-rescue” service reproduces and analyzes embedded Linux kernel, middleware, application, and hardware problems and bugs, and then offers corrective action and performance improvement solutions, says the Japanese embedded firm.

A pioneer in offering commercial embedded Linux distributions in the early part of the decade, Lineo has long experience in failure analysis. In 2000, the company introduced a Lineo High Availability Cluster product based on Linux and CompactPCI hardware that claimed to offer “Five-nines” availability.

Failure analysis for embedded system development is more complex than desktop/server analysis due to the broad array of process flows and the restriction of system resources, says the company. The embedded environment leads to “wide-ranging events” that traditional failure recovery methods may not uncover, suggests Lineo.

Working with any embedded Linux system, the service offers the following features:

  • Reproduce a problem:
    • Deadlock
    • Memory leak
    • Scheduling
      • Process
      • Segmentation fault
      • I/O scheduler
      • Real-time thread
    Analyze and offer a possible solution

  • Correct the problem (including supplying a patch)

In November, Lineo announced a quick-start technology that it claims can boot Linux in 2.97 seconds on a low-powered system. The Warp 2 technology appears similar to but much faster than Linux's existing “suspend-to-disk” capability. Lineo's other current products include a uLinux ELITE distribution and cross-compiling toolchain. The company also offers software reference designs and professional services to OEMs developing systems and products.


Lineo's LL-rescue service is available now for a price of 1.2 million yen (currently $12,768 US).
